Observe the following precautions:
@l Throttle mechanism should be
checked for free movement before
starting engine.
@l Engineshould be running only when
pulley guard is secured in place.
@l Never run engine without drive belt
installed. Running an unloaded en-
gine can prove to be dangerous.
@l Never run the engine when the track
of the vehicle is raised
off the
ground.
@l It can be dangerous to run engine
with the cab open.
@) Since engine cooling is fully ineffect
only when the vehicle is in motion
and driven on snow, it is
not recom-
mended that you allow the engine
to idle for more than brief periods
and
lor you drive the vehicle on icy
surface. Prolonged idling and
lor
continuous driving on ice may cause
engine damage.
@! Gasoline is flammable and explosive
under certain conditions. Always
perform procedures in a well ventila-
ted area. Do not smoke or allow
open flames or sparks in the vicinity.
If gasoline fumes are noticed while
driving, the cause should be deter-
mined and corrected without delay.
@) Your snowmobile is not designed to
be operated on public streets, road
or highways. In most States and
Provinces, it is considered an ille-
galoperation.
@) Maintain your vehicle in top mocha-
nical condition at all times.
@! Your snowmobile is not designed to
be driven or operated on black top,
bare earth, or other abrasive surfa-
ces. On such surfaces abnormal and
excessive wear of critical parts is
inevitable.
2
@) Only perform procedures as detailed
in this manual. Unless otherwise
specified, engine should be turned
OFF for all lubrication and mainte-
nance procedures.
@! Installation of other than "stock"
equipment, including ski-spreaders,
bumpers, pack racks, etc., could
severely affect the stability and
safety of your vehicle. Avoid ad-
ding
on" accessories that alter the
basic vehicle configuration.
@! When removing coolant tank cap,
first place a cloth over cap then turn
cap to its frst step to release
pressure.
@! The snowmobile engine can be
stopped by activating the emergen-
cy cut-out or tether switches, or
turning
off the key,
@) This vehicle is designed tor the
driver only. No provisions have been
made for a passenger.

cates, in thousands,
the number of re-
volutions per minute
(F-lPM) of the
engine.
_CAUTION: The tachometer is
.".. protected by afuse. If tachome-
ter stops operating, check fuse condi-
tion and if necessary, replace. The fuse
is 0.1 amps. Do
not use ahigher rated
fuse as this can cause severe dam-
age to
the tachometer.
The gauge indicates engine coolant
temperature. Normal operating tem-
perature is between 50° to 80° C
(120° to 1800F), (coolanttemperature
can vary depending on driving and
snow conditions). However, should the
pointer of the temperature gauge touch
the red zone, reduce speed and run
vehicle in loose
snow or stop engine
immediately.
WARNING: Before removing the
cap always release the pressure
by placing acloth over the cap and by
partially unscrewing it (first step). If
this is disregarded loss of fluid and
possibility
of severe burns could occur.

With Bornbardier-Hotax engines, a
break-in period of 6to 10 operating
hours is required before running the
vehicle at full throttle. During this pe-
riod, brief full throttle accelerations
and constant speed variation will con-
tribute to agood break-in. Continued
wide open throttle accelerations can be
detrimental. Never let your engine
overheat.
CAUTION: Incorrect or lack a
break-in period will result in engine
horsepower loss.
As with any precision piece of mechen-
ieal equipment, we suggest that after
the first 10 hours of operation or 30
days after the purchase, whichever
comes first, that your vehicle be
checked by your dealer. This inel'st>
tion will give you the opportunity to
discuss the unanswered questions you
may have encountered during the first
hours of operation. Remember that it
is easier to remedy at this time than to
allow the snowmobile to operate until
apossible breakage occurs.
The 10 hours inspection is at the ex··
of the vehicle owner.
